I agree with the other mamma STAY away from them. They are a dark cool place when they are not being used which breeds bacteria, and also going from warm to cold many times causes it to create extra bacteria. I personally have found that they can dry out the wipes as well. I never really warmed the wipes after that for fear of bacteria. But my friend says she sets one or to in the microwave for about 3 seconds....I would think that would dry them out too. I just hold them in my hand for a minute or two until they aren't so cold....and the kids seem to do fine with that. Good luck.
